Question on 3933198 Intake
On a 3933198 Intake, is there suppose to be a 1 inch diameter hole in the casting just to the right of the thermostat location? I am looking at some terrible pictures of one that I might purchase and I can't figure out what this hole is for. I've also had these intakes in the past and I don't remember this hole. Am I just begining to show signs of dementia?
